/clear @a item 0 0
Build:#332621
Impact: Unable to detect a certain item in an inventory such as a quest item or sword. This will break several challenges and the story line in our map and is one of the biggest bugs we have as we have been unable to do a complete test of the map due to this.
Observed Results:
Always gives a successful action back, so you can't have a conditional test for items in inventories
Expected results:
Its should only be true, if a person has that item in his inventory not at all times
